Which statement describes the bonds in iron sulfate, FeSO4? Fe and S have an ionic bond, and S and O have ionic bonds, too.

Fe and S have a covalent bond, and S and O have covalent bonds, too.

Fe and S have a covalent bond, while S and O have ionic bonds.

Fe and S have an ionic bond, while S and O have covalent bonds.

Would be D. Fe and S have an ionic bond, while S and O have covalent.

Hope that helps.
